How to Remove an Old Dishwasher · Step 4 of 6
In this video
Lay the old disposal on its side. Use a screwdriver to remove the electrical cover plate on the bottom of the unit. Unscrew the green ground screw. Untwist the wire nuts connecting the hot (black) and neutral (white) wires. Finally, loosen the clamp holding the armored power cable and pull the cable free from the disposal.
Goal: Safely detach the hard-wired power cable from the old disposal

FAQs
What are the absolute most critical safety steps I need to take before starting this project?
Before anything else, locate and shut off the electrical breaker dedicated to your dishwasher, and turn off the hot water supply valve, usually found under the sink. Verify both are off before touching any wires or hoses to prevent electric shock or water damage.
What specific tools from the list are absolutely essential for a beginner, and are there common alternatives?
You definitely need a Phillips head screwdriver, an adjustable wrench, and a bucket for drips. While specialized tools can help, these three will handle most disconnections. Ensure your screwdriver fits snugly and your wrench isn't stripped.
How difficult is this project for someone with no prior plumbing experience, and how long should it realistically take?
This is considered a beginner-friendly project, primarily involving disconnection. For a first-timer, plan for 1.5 to 2.5 hours, allowing extra time for identifying connections, stubborn fasteners, and safely managing any water spills.
I'm concerned about water leaking everywhere when I disconnect the hoses. How much water should I expect, and how do I minimize the mess?
Expect some residual water (1-2 cups) from the supply line and the dishwasher's sump. Place towels and a bucket directly under the connections before loosening them. Work quickly and have extra absorbent towels, like the WYPALL L40, ready.
